significant negative CC of
0.42 (at 2% level). But Table 1 does not show
any significant relationship between antecedent and succeeding TCI (A-M)
and AIR, NWR, and PIR.
For TCI (A-N), Table 1 shows significant negative CC of
−
0.42
(2% level) between concurrent TCI (A-N) JJA and NWR. The CCs
between July TCI (A-N) and AIR, NWR, and PIR are
−
−
0.47 and
−
0.47
(both at 1% level) and
0.42 (2% level), respectively, while succeeding
relationships show significant negative CCs of
−
0.52
(1% level) between TCI (A-N) of DJF and AIR and PIR, respectively.
However, the antecedent relationship shows significant positive CC of 0.36
(5% level) between TCI (A-N) of May and AIR only.
Concurrent TCI (A-C) does not show any significant relationship with
AIR, NWR and PIR (Table 1). However, succeeding October, November,
and SON show significant positive CCs of 0.37 (5% level), 0.49 (1% level),
and 0.41 (5% level) with AIR; succeeding October TCI (A-C) with NWR
(CC = 0.36 at 5% level), and succeeding November TCI (A-C) with PIR
(CC = 0.40 at 5% level). As far as antecedent relationships are concerned,
Table 1 shows that only February TCI (A-C) have significant positive CCs
of 0.36 (5% level) with AIR and 0.46 (1% level) with NWR. Thus, it appears
that February TCI (A-C) has the potential to be used as a predictor for
Indian summer monsoon rainfall all over India and the northwest India.
For TCI (C-M), Table 1 shows the strong and inverse CCs of
−
0.46 (1% level) and
−
0.70,
−
0.58 (all are significant at 0.1% level) between concurrent
August TCI (C-M) and AIR, NWR, and PIR. Significant negative CCs are
also obtained between concurrent JJA TCI (C-M) and AIR, NWR, and PIR
(CC =
0.66, and
−
−
0.41 (at 5% level),
respectively. Figure 1 shows the year to year relationships between the
anomalies of TCI (C-M) of concurrent August, and JJA and AIR showing
the inverse association between them, while significant negative CCs are
obtained between succeeding October TCI (C-M) and AIR and NWR
(CC =
0.51 at 1% level),
0.49 (at 1% level), and
−
−
−
0.39 at 5% level), respectively. November TCI
(C-M) with AIR shows negative CC of
−
0.41 at 5% level and succeeding
SON with AIR, NWR, and PIR (CC =
0.46 at 1% level,
−
−
0.54 at 1% level with AIR,
0.41
−
−
at 5% level with NWR, and
0.43 at 2% level with PIR). However, there is
no significant relationship between antecedent TCI (C-M) and AIR, NWR,
and PIR.
Considering TCI (C-N), Table 1 shows significant negative CCs of
−
0.38 at 2% and 5% levels between concurrent JJA
and AIR, NWR and PIR, respectively. In addition, significant negative
